trial hopping

Going from one free trial to the next using multiple email adresses because you're too cheap to buy the whole thing.

Zack:"You're so trial hopping."

Dakota: "No I'm not! This is only my 15th trial! How dare you!!"

trial hopper

A person who does not want to pay for a service, so they use multiple email adresses to extend an expired free trial. They usually make new email accounts just for this purpose.
Inspired by Dakotaa.

Dakotaa: "Oh, crap! My third free trial ran out. I better get another one with my other email."

Zack:"Damn girl your trial hopping. stop being such a trial hopper!"
